Genuine Subaru Uprated High Volume 12mm Rotor Oil Pump For EJ20 EJ25 Engines 15010AA310

High-performance oil pump upgrade for Subaru engines, which is designed to improve oil flow and pressure, especially in race and high-performance applications. This enhanced oil pump features a 12mm rotor for increased capacity and larger passages for better flow. It's particularly well-suited for full race engines before transitioning to a dry sump system.

This upgraded oil pump is ideal for engines with larger bearing clearances, as it provides extra cooling to the bearings. Additionally, it benefits engines with wider camshaft journal clearances, as it ensures sufficient oil pressure at idle and lower RPMs.

Furthermore, this pump is useful for engines equipped with an external oil cooler or a remote oil filter, as it helps reduce pressure loss in the system at lower speeds.

This oil pump upgrade is compatible with the following Subaru models:

Impreza
Legacy
Forester
EJ20 and Turbo Variants
EJ25 and Turbo Variants
P1
WRX
STi
Type R
